EN DLESS HOD-E'LEVATO R.

SPECIFICATION forming part of Letters Patent No. 287,013, dated October23, 1883.

Application filed April 10, 1883. (No model.)

To all whom it may concern:

Be it known that I, OLIVER N. EATON, of the city of New York, in thecounty and State of NewYork, have invented a novel and useful EndlessHod-Elevator and Driving-Gear, whereby an improved method ofhod-elevating is introduced, and whereof a specification follows withreference to accompanying drawings, wherein similar letters indicatecorresponding parts in the several views.

Among the difficulties common to the continuous system of hod-elevatingby endless elevators now in use is the danger and damage occasioned bycontinuing the revolution and carrying the hod over the upper pulleys inthe absence or inattention of the laborers To obviate this difficultyand insure safety it has been customary to arrange an alarm or brakeoperated by the hod at a certain point in its as.- cent, and notifyingor stopping the motive power. These safety devices, however, arethemselves liable to damage and inaction, and require the endless bandor ladder to be turned back to disengage the hod and permit its removal.To furnish an endless hod-elevator which by the improved method ofhod-elevating employed shall itself answer all the re quirements ofsafety and dispense with any special appliance for the purpose is one ofthe objects of my invention.

It is another of the objects of my invention to provide a new andimproved hod-carrier, and by adaptations furnish a better endlesshod-elevator than any heretofore used. I also show how rapid 'motivepower may be applied by means of a peculiar combination of gears andsufficient decrease in revolutions obtained betweenthe engineandtheelevator without using an endless screw 5 and I further show how themotive power may be applied more advantageously and conveniently thanever before by means of a novel anduseful combination of bevel-gears.\Vhen thehods are to be attached to the ascending side of the endlesselevator, by seating or hooking them at'their front end 011 a round orinto a link, it is usual for laborers to do this from their shoulders.When the hod is to be seated on a round near its middle and the line ofthe center of gravity of its load, laborers usually have to reach such aposition by first shanking or standing the hod upon the ground or floor,or on asuitable platform erected in front of the elevator, and thenpushing the hod toward the elevator until its bowl is in position safetyat the same time by using an angular,

swinging bail as a carrier.

Figures 1 and 2 are respectively front and side elevations of such ahod-elevator constructed with endless wire ropes and having the angularswinging bails E, suspended in ears 0 c on ordinary clips around theropes. The bail may have a tailpiece, a, with a jaw,

b, adapted to embrace the hod shank or han- Laborers prefer to put thehods on die lower down,for additional support. and se- 7 curity. Whenchains are used instead of ropes, the bails may be hung on the bolts orrivets of the links. In this elevator each hod derives its entiresupport from a single carrier independent of the others, and these maybe affixed at such intervals as are found necessary to admit the hodsand supply the 'de mand. To insure safety and prevent damage in case ofnegligence in removing the hod at the upper station, I make the upperpulleys with separate shafts, B andO, independently j ournaled insuitable uprights, D D, on an ordinary base, and with sufficient spacebetween their adjoining ends to allow the hod to swing through as it iscarried over. If a hod isaccidentally carried beyond its destination, no

harm now results as it is carried over the top and down the otherside,where it can be removed at any point of descent or returned to thebottom. The operation of seating a hod in this angular swinging bail ismost clearly shown in Fig. 2, the dotted lines representing the hod upona laborersshoulder and the bail pulled toward him,for convenience. Theascending bail lifts the hod from his shoulder, and then it swings intothe perpendicular position indicated by the full lines. The operation ofremoving the hod issimilar. I propose to corrugate the sides of thehod-bowl in front of the middle for such space as may be practicallynecessary, (indicated by the dotted lines d d on the hod F. in Fig. 2.)These corrugations may be cut into the wooden sides of the bowl, or

may be furnished by attaching a corrugated strip of metal. Thesecorrugations correspond with the bail, which sinks into them and affordsthe hod a firmer seat. The use of thetail-piece a will obviate anynecessity of these corrugations 5 or they may be used together fordouble assurance against accident. The bail E may be made elastic, sothat the weight of the loaded hod shall cause the arms of the angle or Vto bind against the sides of the bowl or into its corrugations. Thesecorrugations may be continued, also, along the bottom of the bowl, toengage the carrier.

Figs. 5 and 6 show this method adapted to a single-chain endlesselevator, and are respectively front and side elevations. The carrier Vis here an angular bracket, having a claw, g, and suspended at suitableintervals by an eye, h, on a bolt or rivet on the side of the chain,which position utilizes the natural stiffness of the chain to preventlateral sway. The upper pulley, T, is now placed at the end of its shaftU, to allow the hod to swing by when carried over, as shown most clearlyin Fig. 6, which also shows how this claw-carrier catches and holds thehod.

Figs. 3 and 4, being respectively front and side elevations, show anendless-ladder elevator constructed of chains instead of wire ropes buteither chain or rope may be employed and the connections easily adaptedin any ordinary manner by the mechanic. The connecting-rounds R have anear or eye, 6 e, at each end through which they are suspended by thebolt or rivet connecting the links, whereupon they swing easily andalways m aintain aproper position to receive the hod. The central part,f, of such connecting-round is of a V shape, the angle being suited tothe angle of the hod-bowl and of any sufficient depth, two or threeinches usually being enough. The practical operation of this peculiarconstructi on is as follows: A hod is seated upon around in the V, andits handle or shank swings inward against the next lower round, R, andnaturally finds its way into that V which, by the pressure, is more orless swung inward, and forms a notch, f, by which the handle is heldfrom all possible lateral sway. The hod is thus securely and simplyseated for elevating, and is put on and taken off in the usual manner.The rounds, being suspended, always maintain the same upright positionthroughout the revolution.

Fig. 7 shows a novel carrier adapted to a single-chain elevator. Thiscarrier is fixed, and consists of two Vs united at their points, formingan X. This is attached to the side of a link by a bracket or brackets, mm, sufficiently out from the chain to give room for.

gether in one piece of malleable metal. The hod requires additionalsupport from the next lower carrier, against which its shank rests in asuitable notch or between two pins, z i, which can be likewise cast ineach carrier. Attaching the carrier and the hod carried to the side ofthe chain, instead of ondts front, is novel and useful in that itutilizesthe natural stiffness resulting from the construction of thechain to resist the tendency to sway or deviate from a right line ofascent caused by the loaded hods.

Figs. 3 and 4 also show a novel and useful 7 combination ofdriving-gears, whereby the number of revolutions of the endlesselevator, as compared with the number of revolutions of the engine, issufficiently reduced to meet the requirements of actual use. The pulley.S of the engine is connected by a belt or driving-chain, Q, with theloose pulley P on the shaft K. The pulley P and pinion O are fast enedtogether, and both run loose on the shaft K. The pinion O meshes withthe cog-wheel N, fast on the shaft H, which also has fast 011 it, towardthe other end, the pinion L, meshing with the cog-wheel M, fast on theshaft K. The shafts K and H have bearings on any suit- Fastened on thisshaft K, also, are the lower pulleys, driving the endless elevator inthe ordinary way. For example, suppose the diameters of the severalwheels to be as follows: 0 equals ten inches, N equals eighteen inches,L equals four inches, M equals twenty-four inches, S equals six inches,and 1? equals twelve inches. If S runs at two hundred and fiftyrevolutions per minute, then P runs at one hundred and twenty-five, andits pinion O at the same number, while the cogwheel N has only aboutseventy revolutions and the pinion L the same number. The cogwheel M,meshing with the pinion L, therefore, has only about twelve revolutionsper minute, and the driving-pulleys of the elevator the same number. Ifthese driving-pulleys are six feet in circumference, the endlesselevator ascends about seventy feet a minute,

Other combinations can easily be made by any good mechanic to suit thecircumstances.

WVith the driving-gear shown in Figs. 3 and 4, as with the driving-gearswell known in the art, the motive power, Whether man, horse, or engine,must be in line, either in front or back of the elevator, and in eitherplace is in the way of laborers putting on or taking off hods. It ismost desirable in use that the motive power should be at one side, andthis has been accomplished by using an endless screw to transmit thepower; but this is objectionable because of the great friction andconsequent waste of power. I attain this object and avoid this objectionby the use of bevel-gearing. Figs. 10, 11, and 12 show this motivegearing applied to the lower frame-work of an endless elevator, andFigs. 8 and-9 show its Fig. 12 is a plan of the mechanism shown in frontand side elevation in Figs. and 11, respectively.

- modification in combining this bevel-gearing may benecessary'in orderto bring the driving-shaft down to a convenient height for manpower, andsuch modification is shown in Figs. 8 and 9. The bevel-wheel Z mesheswith the bevel-pinion I, having a companion bevel-pinion, J, fastened atthe opposite end of its shaft, which may vary in length according torequirements, and be j ournaled and secured upon the frame-work in anyordinary manner. This latter bevel-pinion, J, meshes with thebevelpinion W upon the shaft Y, to which power may be applied, as beforeEither style of motive gearing may be easily adapted'by any skilledmechanic to driving the single chain or ladder elevator, either at thetop or the bottom.
